招財樹葉子變黃干枯
發(fa)(fa)(fa)(fa)財(cai)樹秋冬(dong)(dong)(dong)(dong)季(ji)養(yang)護溫(wen)(wen)度(du)控制：發(fa)(fa)(fa)(fa)財(cai)樹原產(chan)于(yu)中(zhong)南美洲,因此喜溫(wen)(wen)暖(nuan)(nuan)濕(shi)潤(run)的生(sheng)長(chang)環(huan)(huan)境。其生(sheng)長(chang)適(shi)溫(wen)(wen)是(shi)20℃～30℃,冬(dong)(dong)(dong)(dong)季(ji)越(yue)冬(dong)(dong)(dong)(dong)溫(wen)(wen)度(du)需達(da)到5℃以上,否則容易發(fa)(fa)(fa)(fa)生(sheng)冷(leng)(leng)(leng)害和凍(dong)害。隆冬(dong)(dong)(dong)(dong)季(ji)節,只要環(huan)(huan)境溫(wen)(wen)度(du)保持在(zai)(zai)18℃以上,且(qie)(qie)(qie)光(guang)照(zhao)充足(zu),發(fa)(fa)(fa)(fa)財(cai)樹就可(ke)(ke)正常生(sheng)長(chang)。若室(shi)(shi)(shi)溫(wen)(wen)低于(yu)8℃,且(qie)(qie)(qie)環(huan)(huan)境過(guo)(guo)于(yu)潮濕(shi)、過(guo)(guo)于(yu)干(gan)燥(zao)(zao)或不(bu)(bu)通風時(shi),葉(xie)(xie)(xie)片(pian)(pian)會出(chu)(chu)現水(shui)(shui)(shui)漬狀斑(ban)塊,先呈古銅色,進(jin)而脫(tuo)落(luo);氣(qi)溫(wen)(wen)低于(yu)5℃后(hou),葉(xie)(xie)(xie)片(pian)(pian)全(quan)部脫(tuo)落(luo),嚴重時(shi)整(zheng)株枯(ku)死。因此,一(yi)(yi)般(ban)在(zai)(zai)11月(yue)中(zhong)旬(xun)(xun)將(jiang)(jiang)盆栽(zai)(zai)發(fa)(fa)(fa)(fa)財(cai)樹入室(shi)(shi)(shi)越(yue)冬(dong)(dong)(dong)(dong),第二年“谷雨”以后(hou)出(chu)(chu)室(shi)(shi)(shi)栽(zai)(zai)培。 水(shui)(shui)(shui)分調節：發(fa)(fa)(fa)(fa)財(cai)樹對(dui)水(shui)(shui)(shui)分的適(shi)應性(xing)較強(qiang),在(zai)(zai)室(shi)(shi)(shi)外(wai)大水(shui)(shui)(shui)澆灌(guan)或在(zai)(zai)室(shi)(shi)(shi)內10多天不(bu)(bu)澆水(shui)(shui)(shui),也(ye)不(bu)(bu)會發(fa)(fa)(fa)(fa)生(sheng)水(shui)(shui)(shui)澇或干(gan)旱。但冬(dong)(dong)(dong)(dong)季(ji)盆土要忌濕(shi),以略潮為(wei)(wei)宜,否則葉(xie)(xie)(xie)尖易枯(ku)焦(jiao),甚至(zhi)葉(xie)(xie)(xie)片(pian)(pian)脫(tuo)落(luo)。若室(shi)(shi)(shi)溫(wen)(wen)在(zai)(zai)12℃左(zuo)右,通常一(yi)(yi)個月(yue)澆一(yi)(yi)次(ci)水(shui)(shui)(shui)即可(ke)(ke)。光(guang)照(zhao)條件(jian)：發(fa)(fa)(fa)(fa)財(cai)樹在(zai)(zai)室(shi)(shi)(shi)外(wai)全(quan)陽(yang)光(guang)照(zhao)射環(huan)(huan)境中(zhong)生(sheng)長(chang)健壯,葉(xie)(xie)(xie)節短、葉(xie)(xie)(xie)片(pian)(pian)寬、葉(xie)(xie)(xie)色濃綠(lv),且(qie)(qie)(qie)莖基部肥大壯實。若長(chang)期(qi)在(zai)(zai)弱光(guang)下(xia)生(sheng)長(chang),則枝條細、葉(xie)(xie)(xie)柄下(xia)垂,葉(xie)(xie)(xie)片(pian)(pian)顏色變為(wei)(wei)淡綠(lv)色。因此,盆栽(zai)(zai)發(fa)(fa)(fa)(fa)財(cai)樹越(yue)冬(dong)(dong)(dong)(dong)結束后(hou),從室(shi)(shi)(shi)內轉(zhuan)移(yi)到室(shi)(shi)(shi)外(wai)時(shi),要逐(zhu)步適(shi)應光(guang)照(zhao)過(guo)(guo)程,避免葉(xie)(xie)(xie)片(pian)(pian)發(fa)(fa)(fa)(fa)生(sheng)日灼現象。可(ke)(ke)在(zai)(zai)翌年3月(yue)中(zhong)下(xia)旬(xun)(xun),選擇(ze)晴天的中(zhong)午,將(jiang)(jiang)盆移(yi)出(chu)(chu)室(shi)(shi)(shi)外(wai)。開始(shi)每天直(zhi)(zhi)接見陽(yang)光(guang)1小時(shi)～2小時(shi),之后(hou)逐(zhu)步延長(chang)光(guang)照(zhao)時(shi)間,直(zhi)(zhi)到恢復(fu)全(quan)日照(zhao)管理。防止煙(yan)熏冬(dong)(dong)(dong)(dong)季(ji)室(shi)(shi)(shi)內養(yang)護期(qi)間,要注(zhu)意避免植株遭受(shou)煙(yan)熏。煙(yan)熏會導(dao)致葉(xie)(xie)(xie)片(pian)(pian)發(fa)(fa)(fa)(fa)黃,直(zhi)(zhi)接降(jiang)低發(fa)(fa)(fa)(fa)財(cai)樹觀賞價(jia)值。冷(leng)(leng)(leng)害補(bu)救：如果發(fa)(fa)(fa)(fa)財(cai)樹在(zai)(zai)冬(dong)(dong)(dong)(dong)季(ji)防寒不(bu)(bu)到位,很(hen)容易遭受(shou)冷(leng)(leng)(leng)害。在(zai)(zai)冬(dong)(dong)(dong)(dong)季(ji)或早春(chun),當氣(qi)溫(wen)(wen)降(jiang)至(zhi)3℃～4℃時(shi)會使葉(xie)(xie)(xie)片(pian)(pian)遭受(shou)冷(leng)(leng)(leng)害;氣(qi)溫(wen)(wen)降(jiang)至(zhi)0℃以下(xia),根(gen)部也(ye)會受(shou)害。冷(leng)(leng)(leng)害癥(zheng)狀一(yi)(yi)出(chu)(chu)現,應迅速(su)將(jiang)(jiang)其移(yi)至(zhi)溫(wen)(wen)暖(nuan)(nuan)處。若僅是(shi)葉(xie)(xie)(xie)片(pian)(pian)受(shou)害,可(ke)(ke)用萘乙(yi)(yi)酸丁(ding)酯、赤霉素(su)溶液噴灑葉(xie)(xie)(xie)片(pian)(pian),同時(shi)用萘乙(yi)(yi)酸等(deng)藥(yao)劑(ji)灌(guan)根(gen)。每3天處理一(yi)(yi)次(ci),等(deng)嫩葉(xie)(xie)(xie)長(chang)出(chu)(chu)后(hou),改為(wei)(wei)7天一(yi)(yi)次(ci),一(yi)(yi)般(ban)5次(ci)～6次(ci)即可(ke)(ke)恢復(fu)。當發(fa)(fa)(fa)(fa)現根(gen)部受(shou)害時(shi),可(ke)(ke)灌(guan)注(zhu)濃度(du)為(wei)(wei)70%的乙(yi)(yi)一(yi)(yi)錳可(ke)(ke)濕(shi)性(xing)粉劑(ji)200倍液,然后(hou)將(jiang)(jiang)植株放在(zai)(zai)溫(wen)(wen)暖(nuan)(nuan)干(gan)燥(zao)(zao)處恢復(fu)生(sheng)長(chang)。...
